I have a pretty decent guy who had some nice Chevelle's and a super clean 66 Caprice. He is asking what I would charge to swap out his 327 and put in a 6.0 I asked why he wanted do that, his answer was "everyone else is and the LS engines drive better" What??? I did tell him with a new FI injection setup as I will not mess with old GM wiring and pcm junk will cost the most and the carbureted will be less. He was thinking 5-700 bucks, LMFAO I told him that might get the tank and fuel lines in but that's about it. All said an done I think he looking at up to 3K for what he wants to do. Heck he spent $4500 to put in his BBC in the '71 Chevelle and the shop could not get it running right and I was the guy that fixed it. That car runs pretty good. So what's a fair charge to to something like this as I have never swapped an LS engine except for the factory ones I did at the stealerships I worked at.
